Rep Power: 0

So I’ve finally gotten back to this project and I got the slxa transmission in, I have all the electrical connections hooked up. I got it to turn over pretty good last night but the battery was dead so only got a few turns, let it charge for an hour or so and went back to try to start it again. This time it just clicked really loud once then nothing afterwards. Now there’s nothing when I turn the key but right after I let go of the key I hear over by the abs 2 clicks. Not really sure what to do from here, starter and ignition fuses are good, going to check the relay and find my multimeter to see if I’m getting power to the starter. Any help or advice is appreciated!
